Description & Features
The CBS-2030e and CBS-2030s series feature patented intermittent spray over technology, which works like this:
The following variables are programmed for each batch size:
™
Brew volume
™
Prewet percent (Percentage of the brew volume)
™
Brew time
™
Prewet delay (The time between prewetting and the brew cycle.)
™
Drip delay (The time between the end of the brew cycle
and the unlocking of the brew basket.)
™
Bypass percent
(CBS-2031s & 2032s only)
(Percentage of the brew volume)
Using these variables, the software calculates how much water to use for prewetting and brewing. The total brew
time is divided into several 30 second cycles. Within these cycles, the software calculates how long to spray water
over the coffee grounds, and how long to pause before the next cycle begins.
Features
All Models:
™ Two fully programmable batch sizes per side
™ Adjustable prewetting cycle
™ Electronically controlled hot water service
™ Brew temperature protection

Installation
(For Qualified Service Technicians Only)
Keys To A Successful Installation
If not installed correctly by qualified personnel, the brewer will not operate properly and damage may result.
Damages resulting from improper installation are not covered by the warranty.
Here are the key points to consider before installation:
Electrical:
™ All FETCO brewers require NEUTRAL. Ground is not an acceptable substitute. Installation without neutral
may cause damage to the electronic components.
™ The electrical diagram is located on the inside of the lower cover.
™ The installation must comply with applicable federal, state, and local codes having jurisdiction at your
location. Check with your local inspectors to determine what codes will apply.
Plumbing:
™ This equipment is to be installed to comply with the applicable federal, state, or local plumbing codes.
™ The water line must be flushed thoroughly prior to connecting it to the brewer to prevent debris from
contaminating the machine.
™ Verify that the water line will provide at least ¼ gallon per minute for the CBS-2031, and ½ gallons per
minute for the CBS-2032 before connecting it to the brewer.
General:
™ Utilize only qualified beverage equipment service technicians for installation. A Service Company Directory
may be found on our web site, http://www.fetco.com.
Installation Instructions
Brewer Setup
1. Review the Dimensions for the unit you are installing. Verify that the brewer will fit in the space intended for it,
and that the counter or table will support the total weight of the brewer and dispensers when filled.
2. The brewer’s legs are shipped inside the brew baskets.
Warning: Legs are to be adjusted for
Remove the brew basket(s) and the coffee dispenser(s).

3. Place the brewer on the counter or stand.
higher than necessary.
4. When the brewer is in position, level it front to back as well
as side to side by adjusting the legs.
5. Remove the lower cover to access the water and electrical connections. Knock-outs are provided in the back
and base of the brewer body for the connections.
Water Connection
1. Water inlet is a 3/8 inch male flare fitting.
2. The brewer can be connected to a cold or hot water line. Cold water is preferred for best coffee flavor, but hot
water will allow for faster recovery times.
3. Install a water shut off valve near the brewer to facilitate service. If an in-line water filter is used, it should be
installed after the water shut off valve and in a position to facilitate filter replacement.
4. Flush the water supply line and filter before connecting it to the brewer.
5. Verify that the water line will provide at least ¼ gallon per minute for the CBS-2031, and ½ gallon per minute
for the CBS-2032, and that the water pressure is between 20 and 75 psig.
5
Electrical Connection – US & Canada
1. Verify that the actual voltage at the electrical service connection is compatible with the specifications on the
brewer’s serial number label. Make sure the electrical service includes neutral.
2. The temperature and water tank fill level are pre-set at the factory. There is no need to turn off the heaters
during the installation process. The heaters are disabled by the control board until the tank is full of water. The
heating process will start automatically when the tank has filled.
3. The CBS-2031 is factory equipped with a 120 V cord and plug. The CBS-2032 has only a terminal block for
connecting the incoming power wires. Consult local codes to determine if a cord and plug can be installed, or if
the unit must be hard wired.
4. A fused disconnect switch or circuit breaker on the incoming power line must be conveniently located near the
brewer, and its location and markings known to the operators.
Warning: To prevent

6. Electrical connections must be secured in-place within the unit to meet

7. Finally, connect the incoming power wires to the terminal block as shown in accordance with applicable codes.

Final Setup
1. Turn on the incoming water supply line and inspect both inside
and outside of the brewer for leaks in all fittings and tubes
2. Turn on the incoming power.
3. Press the brewer’s main power switch, which is hidden behind the
front leg of the brewer. The control panel on/off switch will begin
flashing. Press this switch.
4. Within 6 seconds, the hot water tank will begin filling until the
water is sensed by the probe at the top of the tank. The display will
read “FIL”. The heaters will be disabled by the control board until
the tank is full.
5. While the water is heating, the display will read “LO” and the
actual water temperature will be displayed. After the water has
reached the set temperature, the display will be blank. There is no
“ready” light.
6. Review the Operating Instructions. Brew one full batch (water
only) on each side to confirm proper fill levels. The brewer is
factory set with water only (no coffee) to dispense the correct
amount of water. If the actual volume is slightly different from the
programmed volume, fine tuning the brewer may be necessary.
See #60 – 61 in the Advanced Settings & Diagnostics section.
7. Re-attach the covers after one final inspection for leaks. Look
closely in the top of the brewer at the dispense fittings during this
inspection.
Operator Training
Review the operating procedures with whoever will be using the
brewer. Pay particular attention to the following areas:
1. Always pre-heat the dispensers before the first use of each day by
filling them half way with hot water, and letting them stand for at
least 15 minutes.
2. Don't remove the brew basket until it has stopped dripping.
3. Make sure the dispenser is empty before brewing into it.
4. Show how to attach covers, close, and or secure the thermal
dispensers for transporting.
5. Show the location and operation of the water shut off valve as well
as the circuit breaker for the brewer.
6. Steam from the tank will form condensation in the vent tubes. This
condensation will drip into and then out of the brew baskets. 1/4
cup discharging overnight is possible. Place an appropriate
container under each brew basket when not in use.
7. We recommend leaving the power to the brewer on overnight. The
water tank is well insulated and will use very little electricity to
keep the tank hot. Leaving the brewer in the on position will also
avoid delays at the beginning of shifts for the brewer to reach
operating temperature.

button will extinguish and the BREW button will
continue flashing, indicating that coffee may still
be dripping from the bottom of the brew basket.
8. Before removing the brew basket or dispenser,
visually verify that dripping has stopped.
Notes:
‰ Preheat dispenser by filling at least ½ full with
water at brewing temperature. Allow it to sit for
at least 15 minutes before draining.

It may also be cleaned in a dishwasher – top rack only.
The CSD is held in place by four magnets. To remove it, grasp the bottom
and pull down.
CSD
Spray Plate Versions:
The spray plate should be removed and cleaned to remove hard
water deposits. In areas with extremely hard water, it may be
necessary to do this daily. Weekly cleaning may be sufficient in some
areas.
When cleaning the spray plate, make sure that each hole is
completely free of mineral deposits. Use a toothpick to clean out
each hole. Never use metal objects or abrasives on the spray plate’s
Teflon coating.
